(05.01)How many solutions will this system of equations have? (2 points)

x − 2y = 24
3x − 6y = 72

Select one:

a. No solution

b. Infinite solutions

c. One solution

d. Two solutions

Answers

Answer 1

Answer: 3x - 6y = 72...reduce by dividing everything by 3
x - 2y = 24...notice how this is exactly the same as the other equation....means that the lines are the same line...meaning infinite solutions

Answer 2

Answer:

Answer:

infinite solutions

there are 750 people at a football game. Out of this number, 320 are students. What percent of the people at the football game are not students? Round to the nearest tenth if needed?

Answers

to do this problem you use is/of=percent/100
So:
320/750=x/100
cross multiply
32,000=750x
divide both sides by 750
x=42.66 repeating

ANSWER: X=42.66 REPEATING

You need to use this equation:
part of the whole = percentage x whole (simpler, it is a=pw)
In this case, it would be
320 = p x 750
Because p is the percentage we are trying to find.
You would then divide both sides by 750 to isolate p.
320 divided by 750 is 0.4266, and rounding to the nearest tenth it would be 0.43. Now your equation is
0.43 = p
To make it a percentage you move the decimal to the right two times. That makes your equation
43 =p
So 43% of the people at the football game are not students.
